General description

(EPhos Pd G6 Br) is a G6 Buchwald precatalyst. The G6 precatalysts are air-stable, palladium-based oxidative addition complexes (OACs) that offer an alternative to the previously developed classes of palladacycle precatalysts. Unlike previous generations, the bulkiest biarylphosphine ligand precatalysts are readily prepared. These precatalysts have been shown to be effective for many reactions, including C-N, C-O, and C-F cross couplings.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

The Buchwald G6 precatalysts are oxidative addition complexes (OACs), which exhibit the same advantages as the previous generations of Buchwald precatalysts: quantitative generation of L–Pd(0), thermal stability, air stability, moisture stability, ease of handling, and high efficiency.
